However, Redmayne’s voice isn’t the only treat in store for listeners. The audiobook— which is Audible’s most preordered audiobook ever — will also feature six new magical creatures as part of the reissued version, as well as a new foreword from Scamander, written by Harry Potter scribe J.K. Rowling.

“It wasn’t until I started reading it out loud for the audiobook that I realized how tricky and poetic J.K. Rowling’s use of sounds and language can be,” said Redmayne in a statement earlier this year. “There are some really great tongue-twister words in here! Occasionally, I had to stop recording just because I was incapable of saying the words without either laughing or getting my tongue in a muddle. I enjoyed the challenge and hope listeners can sense that in my narration.”

The audiobook is now available for download via Audible. You can hear Redmayne read entries from the book below.
